'NAD+ peptide' is a common misnomer — NAD+ is a nucleotide cofactor, not a peptide. Here is the accurate research reference including its precursors.
NAD+ (nicotinamide adenine dinucleotide) is a dinucleotide cofactor central to cellular energy metabolism and sirtuin activity. It is not a peptide. The phrase 'NAD+ peptide' is a misnomer that has entered informal circulation. In research supply, NAD+ is stocked alongside its precursors NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside).
Why it appears alongside peptides in research catalogues
NAD+ precursors are commonly co-studied with mitochondrial peptides such as MOTS-c and SS-31 because they intersect on cellular energy metabolism. Cataloguing them together is a research-workflow convenience, not a chemical classification.
